Hi the answer is A, hopefully i helped you
Part 3) <span>Given triangle XYZ as shown at right find YZ rounded to the nearest tenth
we know that
</span><span>the sum of the internal angles of a triangle add up to 180 degrees
</span>so
m∠X=180-[55+29]----> 96°
applying the law of sines
YZ/sin X=35/sin 55°------> YZ=35*sin 96/sin 55-----> YZ=42.49
YZ=42.5 units
the answer Part 3) isYZ=42.5 unitsPart 4)
we know that
OQ/NQ=PR/NR
NQ=4X+(2X+2)---> 6X+2
OQ=2X+2
PR=15
NR=24+15----> 39
(2X+2)/(6X+2)=15/39
39*(2X+2)=15*(6X+2)
78X+78=90X+30
90X-78X=78-30
12X=48
X=4
The answer part 4) isx=4Part 5) A trapezoid is show below. Calculate the measure of angle x. Round to the nearest tenth of a degree
see the picture with letters attached to better understand the problem
we know that
BC=36-28-----> 8 ft
sin x=BC/AC-----> sin x=8/12
x=arc sin(8/12)-------> x=41.81°------> x=41.8°
the answer Part 5) isx=41.8°
Would assume the Polygon is an 18 sided regular polygon.
Exterior angle for regular polygon = 360/n (Sum of angles of exterior angles = 360°)
where n = number of sides.
Exterior angle = 360 / 18 = 20
Exterior angle = 20°
Sum of exterior angle + Interior angle = 180° (Both angles are on a straight line, so the sum is 180°)
Interior angle = 180° - 20°
Interior angle = <span>160°
</span>Hope this explains it.
Answer: A
Step-by-step explanation: Because in a equation there will be an independant variable and the number of hours would be the independent which is t.
The mode of the given data set is 42, becuase mode is define as the number with the must number of responses or result.
The mean of the given data set is 26.89, because it is define as the average of the data set
The median of the data set is 42, it is define as the middle figure when the data set is already arrange ascending or descending.
